What is Ligament surgery?

11:15 - 5 July , 2021


There are four ligaments in the knee: medial or internal collateral, lateral collateral, anterior cruciate, and posterior cruciate, which provide support, stability, and movement to the joint. However, sudden movements, blows, or excessive stretching can break them, and each of the injuries shows a different severity depending on the ligament in question.

  • Rupture of the medial collateral ligament: This is relatively common and usually heals properly in six to eight weeks without the need for surgery, but if it is injured at the same time as other ligaments, it becomes a bigger problem.
  • Rupture of the lateral collateral ligament: it is not so frequent, but sometimes it occurs together with the damage to other ligaments, which complicates its repair and implies surgical treatment. 
  • Rupture of the posterior cruciate ligament: it is not very common and it is not usually serious if it occurs in isolation, and can be treated without the need for surgery, but if it appears together with other injured ligaments, a surgical reconstruction will be required. 
  • Rupture of the anterior cruciate ligament: it is the most serious and the most frequent, requiring surgical reconstruction due to its inability to heal because it is located within the joint. Its recovery ranges from eight to 12 months.

Diagnosis and treatment Ligament surgery

An MRI confirms the diagnosis, the extent, and severity of the injury, as well as the existence of associated damage. It is the best method to correctly diagnose the extent of an injury such as cruciate ligament tear and determine the possible existence of associated injuries.

The indicated treatment is reconstructive arthroscopic surgery, where the torn ligament is removed and replaced by tendon tissue from the patient or from a cadaver.

Potential risks:

  • Chronic knee pain and swelling.
  • Poor healing or graft rejection.
  • Lack of mobility in the joint.

Before surgery:

Surely, your doctor will recommend to carry out a physical therapy program weeks before surgery in order to reduce pain and inflammation, in addition to strengthening the muscles. 

After surgery:

It is an outpatient procedure, so you will probably return home on the same day. You will have to use crutches as indicated by your doctor and also use a splint or knee brace as appropriate. You will need to rest, keep your leg up, and apply ice regularly. 

You will need to follow your rehabilitation program to achieve a proper recovery.
